Trial location(s) East Wubin, WA

West Buntine, WA
Liquid N strategies locations
Aims

To evaluate the effectiveness of different, grower-chosen strategies to apply liquid nitrogen.

Key messages

In all three trials there was no statistically significant yield response to additional post-emergent liquid nitrogen. Given the below average rainfall experienced in the district in this season, this result is probably not unexpected.
